buondua CDN File Downloader

Overview

The CDN File Downloader is a graphical application built using Python and PyQt5 that facilitates downloading files from a CDN server. It provides a flexible interface to either manually input the base URL, token, and file prefix, or automatically extract these details from a full link. The downloader supports multiple image formats, automatically converts non-JPEG formats to .jpg, and includes features like progress tracking, log updates, and the ability to browse for an output folder.

Key Features

• Manual or Full Link Mode: Allows the user to either manually input the necessary details or paste a full link, with auto-extraction of key components.
• Supported Image Formats: The downloader attempts to download files in .jpg, .jpeg, .webp, and .png formats, converting non-JPEG formats to .jpg for consistency.
• Retry Mechanism: Retries up to 8 times for missing files before halting.
• Progress Tracking: Visual progress updates using a progress bar, based on the download attempts.
• Log Output: Real-time log of download attempts and outcomes.
• Multi-threaded: Downloads run on a separate thread to avoid freezing the GUI.

Image Conversion

Files in formats other than .jpg (such as .webp and .png) will be automatically converted to .jpg for easier compatibility and saved in the output folder.

Error Handling

The application is designed to handle request exceptions (e.g., timeouts, unavailable files) and will retry downloading each file up to 8 times before stopping.
